Introduction Of Silica Sand Flotation Separation Process

Introduction Of Silica Sand Flotation Separation Process

Jul 28, 2021 1. Flotation separation of mica minerals and silica sand. Mica dissociates a large number of anions O2- and F- with extremely low zero electric points. After being exposed to the layered structure, they can be recovered with cationic collectors in a wide pH range (pH=2-13). The pH range of feldspar in the cation collection system (pH=4-11) is smaller than that of mica, so mica can preferentially float out under strong acid conditions. 2. Flotation separation of feldspar minerals and quartz sand
